The nasal structure of Plethodon cinereus was studied to determine if there is enhanced development of the vomeronasal organ compared with other salamander families that would correlate with use of these unique features. The vomeronasal organ in salamanders is found in a ventrolateral diverticulum of each main olfactory organ. P. cinereus has a more anteriorly placed vom-Ellen M.
